1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Importance: Women with prior gestational diabetes are at high risk of cardiometabolic disease, including dyslipidemia, early in the postpartum period. Identifying modifiable factors associated with lipid metabolism is clinically important. Objectives: To examine the association between breastfeeding intensity and early postpartum lipid profiles and assess whether these associations persist after adjustment for insulin sensitivity. Design, Setting, and Participants: This prospective cohort study included Japanese women with prior gestational diabetes who underwent metabolic evaluation at 6 to 9 weeks post partum at a tertiary medical center from December 1, 2014, to November 30, 2020. Statistical analysis was conducted from April 2024 to June 2026. Exposures: Breastfeeding intensity categorized using a validated 6-level scale. High-intensity breastfeeding (HIB) was defined as 80% or more breast milk. Main Outcomes and Measures: Fasting lipid profiles and dyslipidemia defined according to Japan Atherosclerosis Society criteria. Associations were evaluated using multivariable regression models adjusting for clinical covariates and insulin sensitivity (Matsuda index). Results: Of 470 women in the study (mean [SD] age, 34.0 [4.8] years), 369 (79%) practiced HIB. HIB was associated with lower mean (SD) triglyceride levels (67.2 [42.0] vs 116.1 [66.7] mg/dL; P < .001), higher mean (SD) high-density lipoprotein cholesterol (HDL-C) levels (73.9 [17.8] vs 63.0 [14.0] mg/dL; P < .001), and lower mean (SD) high-density lipoprotein cholesterol (LDL-C) to HDL-C ratios (1.8 [0.7] vs 2.3 [0.7]; P < .001) compared with those not practicing HIB. In adjusted analyses, HIB was associated with reduced odds of hypertriglyceridemia (adjusted odds ratio [AOR], 0.25; 95% CI, 0.13-0.51) and elevated LDL-C to HDL-C ratio (AOR, 0.27; 95% CI, 0.15-0.49). These associations remained significant after adjustment for insulin sensitivity. Conclusions and Relevance: This study found that HIB was associated with more favorable early postpartum lipid profiles after adjustment for insulin sensitivity among women with prior gestational diabetes, suggesting that greater breastfeeding intensity is associated with a more favorable early cardiometabolic profile among women with prior gestational diabetes.
